Description
Technical field
The present invention relates to use computer system to carry out neurobehavioral and detect the field of evaluating, the method that particularly uses a computer system to carry out neurobehavioral test evaluation to multiple different object of study or research purpose.
Background technology
Neurobehavioral toxicology (Neurobehavioral Toxicology) is a branch of toxicology and Applied Psychology: An International Review.Its developing goal is, " use " experimental psychology and Division 12. Clinical Psychology, behavioral science, and the theory of neuro physiology and method, marshalling is enough to reflect the theory of dissimilar neurobehavioral function status and " test combination " (the test battery) of state, by Epidemiological study means, undesirable element in research environment, particularly neuro chemistry poisonous substance, on the impact of human nerve function, mental status and work capacity.It is the important technical for carrying out the investigation of neurobehavioral functional status and analyzing in neurobehavioral toxicology that neurobehavioral detects assessment technique.Some method that neurobehavioral detects in assessment technique originates from psychometrika (psychometry), but through continuous research and development decades, neurobehavioral detects assessment technique at present has become a relatively independent and complete technology, and has obtained comparatively general application in fields such as preventive medicine, clinical medicine and military medicines.
From angle biology, behavior (behavior) refers to the activity that adapts to meaning that has perceiving from outside.Not only comprise the motion (as run, attack) of health, also comprise static posture.The change (for better hidden) of some animal by body colour and represent some special mark of health or send the category that special cry (to attract the opposite sex) etc. all belongs to behavior.
For the mankind, behavior is mainly divided into two large classes: instinctive behaviour and social behavior, the former refers to congenital heredity, without study can occur typical case, mechanical, sizing behavioral pattern, and be autotelic directivity behavior, as ingest, drink water, defence, property, sleep, maternal behavior and curious etc.The latter refers to that allogenic animal evokes, with the influential behavior of other members to of the same race, as family, school, group, medical treatment, health behavior, human communication behavior, leader and retinue, invasion and attack etc.In addition, the mankind's emotion also belongs to category of behavior, and as pleasure, anger, sorrow, happiness etc., it is the another kind of form of expression of behavior.Neurobehavioral toxicology is more paid close attention to instinctive behaviour.
The behavior of body is subject to the control of nervus centralis, after body is subject to the stimulation of some factor in inside and outside environment, integrate, process through central nervous system, and become mobility's output of coordination, or be stored in the nerve basis that becomes study, memory in central nervous system.This in central nervous system's presence, received information by various sensory nervous systems inside and outside body, and integrate, process by central nervous system, and send exercises instruction, be referred to as neurobehavioral until finally complete the process of this instruction.And this process strong, weak and whether be exactly accurately nerves behavioral ability.Neurobehavioral detects by the description to this course of reaction, and judges neural abnormal change according to some slight change in this course of reaction, and further research and analysis cause the reason of this change.
Early stage neurobehavioral detects and evaluates is some individual event object evaluation methodologys for certain neurobehavioral function mostly, during as visual reaction time, hearing reaction and listen number apart from range etc.Eighties of last century beginning of the sixties, Finland Occupational Health Institute psychologist Haninnen has taken the lead in being compiled into the neurobehavioral test combination that first set is evaluated for organic solvent contactee behavioral function in the world, and bind into book form in writing in 1979, be named as " for the performance testing combination of poisonous substance-psychological study " (Behavioral Test Battery forToxic-psychological Study).Within 1986, the expert of World Health Organization (WHO) (WHO) is releasing the most basic a set of NCTB (NeurobehavioralCore Test Battery, NCTB) after repeatedly studying.This test macro have expend low, method simple, easily accept, the advantage such as culture background impact is less.Early stage neurobehavioral detects and evaluates is all to adopt manual test substantially, because experimenter is grasping the technical difference of test evaluation, causes the comparability of testing result between different experimenters relatively low.Eighties of last century U.S.'s neurotoxicology Baker of man in 80 year mid-term and Letz comment system (Computer-admistered Neurobehavioral Evaluation System by having developed first cover computerization neurobehavioral test in the world cooperatively with computer professional, NES), make neurobehavioral test realize the automatization of sequencing, standardization and record, thereby neurobehavioral testing result credibility is greatly improved.
Current neurobehavioral test comments system conventionally to have the storehouse of a test item, wherein has multiple test items.Way is that each tester is carried out to all test items, and a problem of this way is to take too much computer resource.This is because for specific object of study or research purpose, be not all test items be all necessary.
Another kind of way is according to different object of study or research purpose, selects a part of test item in storehouse to detect, and sometimes also will some specific parameters be set for some test item.The problem of this way is, in the time having multiple researcheres to complete similar detection, cannot guarantee that the testing conditions that different researcheres carries out in different time, place can be consistent, thereby weaken the comparability of the testing result that different testing staff, different time and place complete.

Second embodiment of the invention relates to a kind of neurobehavioral test evaluation methodology.
The second embodiment improves on the basis of the first embodiment, and main improvements are: in to template, each neurobehavioral test item carries out having increased before the step of official testing understanding judgement and the simulation test function of tutorial message.Each details that the first embodiment is mentioned can be used in the present embodiment, in order to make application documents more succinct, just no longer each details has been repeated here.
The entire flow of the second embodiment as shown in Figure 3.
In step 301, system is according to the input selection template of user's (being researcher).Researcher can be set up different detection templates according to different object of study or research purpose
After this enter step 302, system reads neurobehavioral test item and the parameter in selected template.
After this entering step 303, has system judged whether to complete test events all in template? if it is finish this testing process, otherwise enter step 304.
In step 304, the tutorial message of system plays neurobehavioral test item, the method for broadcasting has multiple, for example:
The recording that broadcasting comprises tutorial message or video;
Use speech-sound synthesizing function module to read aloud the tutorial message of text;
Show the text and/or the picture that comprise tutorial message;
Etc..
After this enter step 305, system judges whether Comprephension instruction information of this experimenter according to experimenter's input.If experimenter understands, enter step 306; If experimenter does not understand, enter step 307.
Judge experimenter whether the method for Comprephension instruction information have multiple, for example:
Scheme one: the information the judgement whether expression of inputting by experimenter is understood.Can be to provide a dialog box, experimenter thinks that oneself having understood tutorial message just presses " understanding " button, otherwise just presses " not understanding " button.
Scheme two: by a simple test is provided, and judge according to the response value of this simple test whether information is known in correct understanding to experimenter.Judge whether Comprephension instruction information of experimenter by the response value of simple test, the result of judgement is more objective.
In step 306, enter the official testing of this neurobehavioral test item.Its flow process as shown in Figure 2.After this get back to step 303.
In step 307, enter the simulation test of this neurobehavioral test item.Compared with official testing, simulation test logging test results more briefly and not in process.Complete after simulation test, enter step 306 and carry out official testing.
More brief in process for simulation test is described, give some instances below.
Taking " twin words association " this test item as example, when official testing, can use 12 compositions to phrase, in the time of simulation test, can only form phrase with six, but the mode of operation is the same with judgment criteria and official testing.
Taking " listening simple reaction time " as example, in the time of official testing, experimenter will hear a kind of continuing and more stable musical sound, will occur at random during this time another kind of different sound again.In the time of simulation test, another kind of sound can occur quickly by user, avoids occurring or not for a long time the situation of another kind of sound.
Taking " stereoscopic vision " as example, the picture using when simulation test should be more simpler than official testing, more easily correctly identified by experimenter again.
Employing is similar to method above, and most test item can have the version more more brief than official testing, just enumerates no longer one by one here.
The significance of simulation test is: can not only make experimenter effectively overcome study effect, can effectively avoid the bias on detection method is understood to cause false, bad testing result simultaneously, improve accuracy and the verity of neurobehavioral test result.From technical standpoint, with respect to overcoming study effect by official testing repeatedly, analog detection, because it is more brief and need not calculate test result, can reduce the working time of the computer system for testing on the whole, reduces the resource consumption of computer system.
Further comprising the steps of in the process of carrying out simulation test:
If experimenter's input error, the show needle information wrong to this.By show in time information targetedly in the time makeing mistakes, can make experimenter learn quickly the operational approach of this test event, reduce the consumption of resource for computer system.
If do not obtain the input from experimenter in scheduled duration, show the information of next step operation.By do not know from what start with or carry out the prompting of next step operation when irresolute, can make experimenter learn quickly the operational approach of this test event, reducing the consumption of resource for computer system experimenter.
Method embodiment of the present invention can be realized in software, hardware, firmware etc. mode.No matter the present invention realizes with software, hardware or firmware mode, instruction code can be stored in the memorizer of computer-accessible of any type (for example permanent or revisable, volatibility or non-volatile, solid-state or non-solid-state, medium of fixing or change etc.).Equally, memorizer can be for example programmable logic array (Programmable Array Logic, be called for short " PAL "), random access memory (Random Access Memory, be called for short " RAM "), programmable read only memory (Programmable Read Only Memory, be called for short " PROM "), read only memory (Read-Only Memory, be called for short " ROM "), Electrically Erasable Read Only Memory (Electrically Erasable Programmable ROM, be called for short " EEPROM "), disk, CD, digital versatile disc (Digital Versatile Disc, be called for short " DVD ") etc.
Although pass through with reference to some of the preferred embodiment of the invention, the present invention is illustrated and described, but those of ordinary skill in the art should be understood that and can do various changes to it in the form and details, and without departing from the spirit and scope of the present invention.
